Itmsoil launches new data logger

Reliable readings are the main benefit of a new data logger and read-out unit launched by geotechnical instrumentation and monitoring specialist Itmsoil, following extensive testing on construction sites around the world.

The VWnote uses Fast Fourier Transformation to deliver not just reliable readings but also the ability to check the quality of the readings and the facility to reject them if there is too much interference.

According to Itmsoil, the VWnote will read almost any commercially available vibrating wire (VW) sensor due to its default wide sweeping range, and default or custom configuration facilities. The readings can also be displayed in raw and engineering units.

Another development is the ability to take and store readings without the need for a computer on site. A USB pen drive, supplied as part of the package, can be used to download readings which are stored in the VWnote’s 2GB internal memory - enough for six million data sets. The VWnote can also be configured using the pen drive - the only time a PC is needed is to analyse readings, which can be done using an Excel spreadsheet.

Itmsoil says the device which is powered by four AA batteries, is designed to take the strain out of reading a variety of VW sensors in remote, inaccessible or large sites.
